DIN EN856-4SP Wire Spiral Hydraulic Hose

EN 856 4SP four spiral steel wire hydraulic rubber hose is suitable for high working pressure environment due to its high-strength steel wire spiral reinforcement. In terms of structure, it is almost similar to EN 856 4SH four hydraulic hose, but at the same temperature, EN 856 4SH hydraulic hose can withstand higher working pressure than EN 856 4SP hydraulic hose.
